In Figs. 4 and 5 it is shown top ofthe bottle, showing the frozen contents applied to a bottle, where itwill be seen that 10 seat 8 in the conventional wa The closure isymaintained in position on the bottle by means of a rubber band 9 whichis preferably of circular cross-section or other similar resilientsecuring means which v is applied over the skirt 3 of the closure'nearits lower end. i

In freezing weather when the frozen milk 10 is expanded, as shown inFig. 6 and is projected out of the mouth of the bottle, it tends toforce the losure upward. Since the material of the closure has a smooth,slippery surface that is in contact with the smooth surface of thebottle, the closure, including the attached paper disc or discs, ismoved bodily upward under the pressure of the frozen milk, substantiallyas shown in Fig. 6. The rubber retaining-member 9 being preferably ofcircular cross-section applies sufficient pressure to .normally hold theclosure ind place, yet is sufliciently yielding in its pres-A sure topermitupward movement of the closure under the pressure of the frozenmilk. When the closure is moved upward under the pressure of the frozenmilk 10 it usually carries'the rubber band 9 upward with it until theband impinges against the under part ofthe bead or rim 11 provided onthe bottle, as shown in Fig. 6, whereby further u ward movement of theband is prevented. T- e circular cross-section of the band 9 permits theslippery Cellophane paper to slide easilyl under it, while it isprevented from upward movement by its .abutment against the under sideof the bottle bead or rim 1l, andit mere 1y turns over or rotates whilethe closure sheet isfmoved' upward under it by the pressure of thefrozen milk.- A Y It will be seenthat this bodily upward movement of theclosure enables the end or I mouth of the bottle to be covered or closedat all times, thus protecting that part of the c frozen contents whichis extended out of the mouth of the bottle by expansion in freezing.

Also, even should the cover disc or discs be` dislodged in handling thebottle, the Cellopha-ne covering will ,still enclose the bottle mouthand prevent spilling of the contents. v v

What I claim is:--

1. A bottle closure composed of asheet of f viexible slippery-surfacedtransparent material fitted over the top of a bottle and formed with askirt portion extending downward on the neck of the bottle, andresilient means for holding the closure on the bottle neck', saidresilient means permitting an upward shifting movement of the closurerelative to it' under the pressure of frozen contents of the bottle.

' 2. A bottle closure composed of a section of 3. A bottle closurecomposed of a section of y slippery waterproof sheet material foldedover the top of a bottle and extending down'- ward on the neck of thesame, and securing means surrounding that portion of the closure locatedon the bottle neck, said securing means applying elastic pressure on theclosure and permitting an upward sliding movement of the same beneaththe securing means when receiving the pressure of the frozen contents ofthe bottle. y

4, bottle closure composed of a Cellophane sheet folded over the top ofa bottle to close the mouth of the same, and a rubber retainin -ringapplied to the bottle neck over the Ce lophane sheet ythe rubberpermitting the sheet to slide u ward beneath it under the pressure offrozen Ibottle contents.

5. A bottle closure composed of a cardboard disc, a Cellophane sheetlarger than the disc secured to the same and extending downwardtherefrom about a bottle neck, and a retaini`ngmember holding theCellophane sheet on the bottle, said retaining member per mitting abodily upward movement of the sheet and attached disc relative to theretaining member under the pressure of frozen contents of the`bottle. r

6. A bottle closure composed of a sheet of inelastic, transparentmaterial adapted to fit over the mouth of a bottle and extend down .wardon the bottle neck, means for resiliently holding that part of the sheetwhich extends on the bottle neck, and a dise located on each side of thesheet,`the discs being secured together with the sheet between them andseatinfJr in the mouth of the bottle.

A`bottle closure composed of a sheet of Cellophane or a material of likecharacterisktics folded over the top of a bottle to close the mouth ofthe same, said sheet when folded presenting a skirt portion extendingdownward on the neck of a bottle, and retaining lll movement ofthe'sheet from beneath the re- I taining means Aunder the contents ofthe bottle. v
